TIRE EILLER AND TESTER.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed March 20, 1319. Serial No. 283,929.

To all whom 'it ma? concern:

Be it known tiat we, CHARLES WALTER PELTON and JOHN PORTER BAnoUn, citizens lof the United States, and residents of Livingston, in the county Vof Park and State of Montana, have4 invented. certain new and useful Improvements in Tire F1llers and Testers, of which the following is a specification.

Our invention relates to devices tor Afilling and testing tires, more particularly automobile tires, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object o'i' our invention is to provide a tire air chuck and gage holder combined in one device which when connected with a source of compressed air will deliver the air into the interior of the tire or will cut oit' the air from the tire and put the latter.

in communication with a tire gage so that the pressure within the tire maybe readlly ascertained, said device being operated by a slight manual movement. 'l

A further object of our invention 1s to provide la Itire filler and tester in which the manual movement `which shifts the communication from the tire to the source oi compressed air over to the gage and vice versa, is effected by 4valves which act in stantly, thereby reducing the time of operation to a minimum.`

A, further object of our invention is to provide a device of the type described in which the valve stem of the tire is applied to a single-,opening of the device and in which communication between the source oi compressed airv Ioi' the gage may be et'- fected at will', while the valve stem is applied at the single opening.

A further object of our invention is to provide a device of the type described which is compact, handy to operate, and

lrelatively simple in construction.

@ther objects and advantages will appear in the following specification and the novel features of the invention will be particu.

larly pointed out in. the appended claims'.

Our invention is illustrated in the accomn panying drawings forming part oi this application, in whichz- Figure 1 is a plan View of the device, Fig. 2 is a side elevation,

Fig. 3 is a section along the line 3-3 of' Fig. 1,'tlie pressure gage being omitted,

Fig. 4 is a section along the line 4-4 of 7 v Fig. o is a detail view of one of the valves,

shown therein a device consisting of a main body portion 1 which is preferably made of metal. As will be seen from Fig. 3, the body portion is provided with a here 2 and a smaller opposed bore 3 in axial alinement therewith and extending in from the opposite side of the body portion. In the normal position of the device, the bore 2 will extend upwardly from the bottom and the bore 25 downwardly from the top. A bore flextends downwardly from thetop, as shown in Fig. 3. l,

Disposed within the bore 2 is a valve which. is provided at its lower end with a recess (3. The valve 5 has a central channel or passage 7 extending therethrough. The

terior ofl the bore,2,the upper part being reduced and being provided with a flange H as seen in Fig. 4, having recesses i) for the passage of air. A stud l() has a threaded portion which screws` into the body portion or' the valve as shown in Fig. 2i, this stud having a central channel to permit the passage of air, the lower portion of the stud being'adapted to engage the small check valve in the valve stein of a pneumatic tire. ln lthe bore 2 is a spring l1 which bears on the valve 5 in the' manner shown at one end, and on a gasket l2 ati/the other end.

lVithin the bore 'l is disposed gasket lf3 which i'ornis a seat for the valve 14. rllhe latter is ot' the shape shown in Fig. 'It will. be noted that the central portion of the valve is slightly undercut to ailiord a firm seat all around the edges of the valve head. The valve is provided with a stein 14k which extends through an opening 15 adapted to 4establish communication between 'the bores 2 and 3. A screw plug i6 closes the upper end of the bore 3.

The bore 4 is designed to receive al sleeve 17 which is screw threaded at 'i8 to hold it to the body portion. A bore 19 communicates at one end with the interior of the Alower part of the valve closely fits the in'- bore 2, the other end being closed by a screw plug 20. The bore l) communicates with the interior oi the bore 4 by ineens oi` a, passage 2i. The body portion is provided with an integral stein 2Q which has a passage 22@ communicating with the bore l'roin the foregoing fflescription of the various par ci the device., the operation thereof may be 'cadily understood. The stein 22 ot the ire tester and filler is connected with any suitable source of coinpressed air as for instance the tube 23 leading to the source I(not shown), and a tire gage 2% (see Fig. 2) suoli as a Schrader standard tire gage or other gages, is disposed in the sleeve 17, `When it is desired to ascertain the pressure within the tire, the device is applied Ato the valve stein of the tire, the vstud l() opening7 the check valve and thereby permitting` the pressure within the tire to canse the gage to register, this pressure being transmitted through the stud 1G, the passage i', the bore 2, passages 19 and 2l, into the interior oi the sleeve l?. If the tire needs more intlation, then the body portion is pressed downwardly onto the val stem. This forces the upfalve o wardly against the tension of the spring 1l. The bod;Y portion ot the valve :i closes the passage l, thus cutting oli the gage and the upper end oi' the valve engages the lower portion ot the valve stern 14kt, lifting 'the valve oli' of its seat and permitting air from the storage tank which has l1eretofore been kept back by the valve lei, to pass the valve 14. and to pass through the valve 5 into the interior oi thel tire. 'lilhen the body portion .l is raised the spring ll will force the valve 5 dounwardly, thus swinging the valve le and permitting it to seat on the gasket l?, so as to rut oll` connuunieation between the tire and. the source olz air. The movement oi the valve i? will again uncover the end of the passage lf) so asvto permit the gage to register the pressur( ln order to prevent the valve 'from being' torced out of the bore, we provide the screw 25 whose end entends underneath the liange 5u so as to permit the valve to he brought to the posi.- tion shown in Fig. 3, but no farther.- lVhen the device is removed .'lrorn the valve stein of the tire., the clucltivalve of course closes in the ordinary mannen.

Vle are aware that devices for filling and testing tires are not broadly new, but in the present instance it will. be observed that there is only one opening through which the air iiows from the body portion ol.2 the device into the tire. lt is not necessary to remove the device by changing iirom the gage to the pressure tank. All that is necessary is to use a slight pressure and to relieve the pressure when one can establish connnunicL tion between either the gage er the i'nessure tank at will. The device operates :'lccurately inseriti and guidi/(ly, as well as noiselessly, the lcets l2 and 13 aiding in rendering the de- `vice noiseless, since the gasket 'i2 cushions the end of the valve 5 when the latter is pushed upwardly, :ind the gasket i3 provides a noiseless seat for the valve li.

A tire filling and testing device coinprising a hollow body portion having an opening adapted to receive the valve stem of a pneumatic tire, e pressure gage carried by the body portion, means oradmitting air under pressure to said hollow body portion, and a, pair of valves within said body portion for establishing communication between the tire and said gage, or between the tire and source of compressed air, at will, one ot said valves being operated by the movement of seid body portion relative to said valve stem, and the other valve being operated by a movement of said first named valve.
